The ones I installed on the bines was TSPerformance on the 9 litres,no problems.
On the tractors with the 9 litre I have installed tsperformance with a few exceptions were ok.
If there was a problem could use a unit from DSG Canada that would work with no codes .
The ones from DSG cost a little more.
put a ts performance chip on 06 9660 this year, and when the dial was turned up over 2/3 it would cut the power in half, and smoke like and old 760 massey. kept it turned up just over half, maybe a little more power, but not enough to say it really a noticable difference.
The directions that comes with that box says after install to turn knob clockwise till it makes the engine run funny or thro a code then back it down.
So I guess you got that part right.
I have found that some machine can't handle the extra fuel and others work better with different boxes.
That is why I am a dealer for TS Performance,DSG and Steinbaur.
